These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

along with the rapid development of network technology and terminal technology, intelligent terminal has become the indispensable articles for use in people's daily life, and the frequency that the user used intelligent terminal is also higher and higher, and intelligent terminal brings very big convenience for user's life. However, malicious files with viruses are also very common in some web sites, since there are no very strict regulatory constraints. In the existing implementation, antivirus software is usually installed in an intelligent terminal, and after the file downloading is completed, the antivirus software can be operated to scan the downloaded file so as to judge whether the file is a virus file. In this way, since the intelligent terminal is required to be provided with antivirus software, the space of the intelligent terminal is occupied; if the intelligent terminal is not provided with antivirus software, the virus file cannot be identified, and the safe use of the intelligent terminal cannot be ensured.

The scheme provided by the embodiment of the disclosure is different from the conventional means of judging the virus file by the intelligent terminal in the related art, but the file can be downloaded by the network equipment connected with the intelligent terminal, and the file identification of the downloaded file is provided for the server side to carry out security verification. The server can pre-store the identification of the virus file, so as to quickly judge whether the downloaded file is the virus file, and send a prompt message to the network equipment, and the network equipment can perform corresponding processing according to the prompt message. According to the embodiment of the disclosure, antivirus software does not need to be installed on the intelligent terminal, and the intelligent terminal can be prevented from being infected by viruses. The embodiments of the present disclosure are explained in detail below.

fig. 1A is a diagram of an application scenario of file processing according to an exemplary embodiment, where fig. 1A includes a smart phone and a smart tv as smart terminals, and a router and a server as network devices.

The network device is a device connected to each local area network or wide area network in the internet, and may be an interconnection device in a network layer, and may be configured with a processor, a memory, and other devices, so that the device has a computing function, a processing function, and a storage function, and may be, for example, a router and the like.

the server may be a server, a server cluster, a cloud server, or the like. The server of the embodiment of the present disclosure may be a server corresponding to a router.

The intelligent terminal can be a terminal such as a smart phone, a tablet computer, an electronic book reader, a personal digital assistant, a smart television or a personal computer, and can be provided with a communication component which can be accessed to a wireless or wired network based on a communication standard.

As shown in fig. 1B, is a flowchart of a file processing method shown in the present disclosure according to an exemplary embodiment, including the following steps 101 to 106:

in step 101, the intelligent terminal initiates a file download request.

in step 102, the network device downloads the target file in response to a file download request initiated by the electronic device.

in step 103, the network device obtains the file identifier of the target file and sends the file identifier to the server.

In step 104, the server receives the file identifier, and performs security check on whether the target file is a virus file or not by using a pre-established file library according to the file identifier. Wherein, the file library records the file identification of the virus file.

in step 105, according to the security check result, a prompt message for indicating whether the target file is a virus file is sent to the network device.

In step 106, the network device receives the prompt message; and according to the indication of the prompt message, carrying out corresponding response processing on the file downloading request initiated by the intelligent terminal.

in the embodiment of the present disclosure, various applications may be installed in the intelligent terminal, and a user may obtain application functions by using different applications, for example, browsing a web page by using a browser application, downloading an application by using an application mall application, downloading an audio file by using a music playing application, or downloading a video file by using a video playing application. The application usually displays an option or a control and the like for user triggering on a terminal screen, when a user needs to download a file, the user can trigger the option or the control and the like, and the intelligent terminal initiates a file downloading request to the router.

the router may use the scheme provided by the embodiment of the present disclosure, and start downloading the file when detecting the file downloading request initiated by the intelligent terminal, and the embodiment of the present disclosure refers to the downloaded file as the target file. After the target file is downloaded, the intelligent terminal can send the file identifier of the target file to the server.

The file identifier is a unique identifier of a file, and in practical application, the file identifier may be a file name, a custom numerical value, or any combination of character strings, as long as different target files can be distinguished.

The server may create a file library in advance, for example, collect virus files in advance, and record file identifiers of the virus files. The server compares the file identifier of the target file with the file identifier of the virus file, so that whether the target file is the virus file can be determined. The method is easy to implement, and the virus file identification efficiency and accuracy are high.

In an alternative implementation, the file identification may be a HASH (HASH) value.

The HASH value is a value obtained by logical operation based on the content data of the file, and HASH values obtained from different files (even the same file name) are different, so that the HASH value can be understood as the identification card of the file. Files with different HASH values are considered to be different files, and the contents of files with the same HASH value must be identical (even if the file names are different). Since the HASH value is generated by a series of transformations of the file content by the binary code, the HASH value does not change even if the file name changes, and thus the HASH value has a file check function, which is equivalent to a check code of a file. In the embodiment of the disclosure, when the server stores the identifiers of a great number of virus files, the HASH value serving as the file identifier can ensure the uniqueness of the file.

and the server side can obtain the safety verification result that the target file is the virus file or the target file is the safety file after the safety verification that whether the target file is the virus file is carried out through the file identification. According to the security check result, the server may send a prompt message to the router, where the prompt message is used to indicate whether the target file is a virus file.

In this embodiment, the router receives the hint message, and since the hint message indicates whether the target file is secure, the router may perform corresponding response processing. In an optional implementation manner, the performing, according to the indication of the prompt message, a corresponding response process on the file download request initiated by the intelligent terminal includes:

If the target file is a safe file, the downloaded target file can be sent to the intelligent terminal;

If the target file is a virus file, the virus reminding message can be sent to the intelligent terminal to replace the downloaded target file so as to inform the user that the target file is infected by the virus, so that the purpose of intercepting the virus file is achieved, and the safe use of the intelligent terminal is ensured.

In an optional implementation manner, when the server establishes the file library, the server may further collect a security file corresponding to the virus file. The purpose of collecting the security files is to provide the security files to the intelligent terminal after the target files are determined to be virus files, so that the intelligent terminal can download and acquire the corresponding security files. When the server side obtains the security file, the server side can record the download address of the security file, or the security file is stored in the local server side, and the download address of the security file is generated. And then, recording the association relationship between the file identifier of the virus file and the download address of the security file, and according to the association relationship, when the target file is determined to be the virus file, quickly acquiring the download address of the security file corresponding to the virus file, so that when a prompt message is sent to the router, the prompt message can carry the download address.

After the server side obtains the security file, in order to distinguish different security files, the file library can also record the association relationship among the file identifier of the virus file, the file identifier of the security file and the download address of the security file. The document library may be pre-established as follows:

Collecting virus files and obtaining file identifications of the virus files; collecting a security file corresponding to the virus file, and acquiring a file identifier and a download address of the security file; and recording the association relation among the file identifier of the virus file, the file identifier of the security file and the download address of the security file.

In practical application, the file library may record the association relationship in a manner of a relational database. Relational databases store data based on relational schema and digitally process database organizations by recording correspondences between data in a data table, where each row of records (i.e., each record) in the table is a tuple and each record relates to N data, and is referred to as an N-tuple. For example, the following shows a data table in an embodiment, which records association relationships between file identifiers of three virus files and download addresses of the security files:

evilsha	downloadur
		evilsha1	downloadurl
evilsha2	downloadur2
		evilsha3	downloadur3

As can be seen from the data table, the binary < evilsha1, downloadurl > indicates the correspondence between the virus file hash value evilsha1 and the secure file download address downloadurl. According to the records, the file library records the hash value of the virus file and the corresponding secure file download address, so that when the server receives the file identifier of the target file sent by the electronic equipment, whether the file is the virus file can be quickly determined through the records of the file library, and further, under the condition that the file is the virus file, the corresponding secure file download address can be quickly obtained.

It can be understood that, in practical applications, other data may also be recorded in the file library at the same time, for example, as can be seen from the foregoing analysis, when the server establishes the file library, the server may collect the security file corresponding to the virus file, and the server may obtain the hash value of the security file as the file identifier of the security file, and then the data may be recorded in the file library in the form of a triple, for example, the triple may be < evilsha, clearhash >, downtladur >, the evilsha represents the hash value of the virus file, the clearhash represents the hash value of the security file, and the downtladur represents the download address of the security file, so as to achieve the purpose of recording the association relationship among the file identifier of the virus file, the file identifier of the security file, and the download address of the security file.

And under the condition that the prompt message indicates that the target file is a virus file, the router can send a virus reminding message carrying the download address to the intelligent terminal according to the download address carried in the prompt message when receiving the prompt message.

In practical application, the virus reminding message sent by the router to the intelligent terminal may be the above-mentioned prompting message, or a message regenerated by the router. The format of the virus reminding message can be in various forms, such as a data packet format, a text format or a text file format.

in an optional implementation manner, before sending the virus reminding message to the intelligent terminal, the method further includes:

In the embodiment of the present disclosure, the virus reminding message may be in a format of a web page (HTML, HyperText Markup Language), and the message in the format of the web page occupies a small space and is easier to parse. The virus reminding message can be generated by adopting a fixed webpage template, the webpage template can be preset according to actual requirements, the webpage template can be pre-stored in the router or a server side, and when the server side determines that the target file is the virus file, the server side can send the webpage template to the router. The router sends the virus reminding message in the webpage format to the intelligent terminal, and the intelligent terminal can directly open the virus reminding message and display the virus reminding message on a terminal screen. The following illustrates a web page template provided by the embodiment of the present disclosure, and fig. 1C illustrates a schematic diagram of a virus alert message displayed in an intelligent terminal.
